Restraint system for a driver of a vehicle

Abstract

A restraint system for a driver of a vehicle comprises at least one protective bar (6), being supported on at least one pillar (2). To achieve an alignment, at least one protective bar (6) is pivotably supported by at least one eccentric (8). The protective bar is lockable.

Description

[0001]The present application claims priority to German Utility model application no: DE 20 2017 005 064.1, filed Sep. 28, 2017.FIELD OF THE INVENTION[0002]The invention relates to a restraint system for a driver of a vehicle, in particular of an industrial truck. Said restraint system comprises at least one protective bar which is supported on at least one pillar of the vehicle.DESCRIPTION OF THE PRIOR ART[0003]A generic restraint system is disclosed in EP 50106605-B. Said restraint system comprises a protective bar which is supported on a rear pillar of an industrial truck. Said protective bar is pivotable between a substantially horizontal restraint position and a substantially vertical released position in order to permit, on the one hand, a secure restraining action and, on the other hand, easy climbing in and / or out of the vehicle. In practice, this restraint system has been repeatedly proved to be expedient and forms the starting point of the present invention.[0004]The objec...

AI Technical Summary

Benefits of technology

[0007]Preferably, the at least one pillar is encompassed by at least one bracket which comprises at least one slot. The at least one eccentric engages in this at least one slot in order to carry out an adjustment of the at least one protective bar transversely to the longitudinal extent of the at least one slot. This design is particularly simple and may also be integrated cost-effectively in restraint systems which are already in existence.

[0008]Since primarily an alignment of the at least one protective bar about an approximately vertical axis is important, the at least one slot is configured to be parallel to the at least one pillar+ / −30°. If, however, an alignment of the at least one protective bar is intended to take place about a horizontal axis, the slot should be aligned substantially horizontally. The internal planar surfaces of the at least one slot in any case ensure that only one movement component is transmitted to the at least one protective bar by the rotational alignment of the at least one eccentric. This permits an accurate adjustment of the at least one protective bar relative to the at least one pillar.

[0010]Alternatively or additionally, it is advantageous if a surface which is curved in a concave manner is provided on the at least one pillar. This surface which is curved in a concave manner is formed in this case so as to be adapted to at least one surface which is curved in a convex manner of at least one support of the at least one protective bar. This results in an advantageous pivot axis for the at least one protective bar, in order to be able to pivot this protective bar in a simple manner. Due to the pivot axis which is forcibly produced, the pivoting of the at least one protective bar may be carried out in a relatively simple manner for the purposes of adjustment. If the aforementioned at least one eccentric is additionally provided, these curved surfaces result in a particularly sensitive angular adjustment by the at least one eccentric. Moreover, this results in the advantage that when pivoting the at least one protective bar the at least one pillar is not subjected to any frictional forces. Thus damage to the at least one pillar when pivoting the at least one protective bar is eliminated.

[0012]In order to be able to fix the support of the at least one protective bar securely to the at least one pillar, it is also advantageous if the at least one support is shaped so as to be curved on either side. In this manner, the at least one support may be easily retained in a clamped manner between jaws, at least one thereof being fixedly supported on the at least one pillar.

[0013]Finally, for the secure fixing of the at least one support it is advantageous if the at least one support is penetrated by at least one retaining means which clamps the jaws against one another. This results in an advantageous pressing action of the jaws against the at least one support, so that the connection of the at least one support to the at least one pillar is optimal.

Problems solved by technology

However, after the restraint system is secured to at least one of the pillars, even slight twisting of the pillars leads to large errors in alignment of the at least one protective bar.

In extreme cases, these errors in alignment may have the result that the at least one protective bar protrudes so far to the side out of the vehicle that said protective bar may become damaged during manoeuvring.

Alternatively, when twisted in the opposing direction the protective bar may also considerably limit the freedom of movement of the driver.
